The Campbeltown and Machrihanish Light Railway was a 2 ft 3 in (686 mm) narrow gauge railway in Kintyre, Scotland, between Campbeltown and the coalmining village of Machrihanish. Only three other passenger-carrying lines in the UK operated on the same gauge, all of them in Wales - the Corris Railway, the short-lived Plynlimon and Hafan Tramway and the Talyllyn Railway.
